Abstract: The carbon tariff is a typically geopolinomic issue and has an economic and environmental influence on the whole world which can not be ignored. By utilizing hybrid programming pattern, the authors have built a global multi-regional Computable General Equilibrium modeling system, which could be used in the analysis of global geopolinomic issues. Based on the CGE simulator developed, the impact of the carbon tariff policy has been analyzed, and the exogenous shock is set as carbon tariff imposed on the developing countries by the United States and European Union. The simulation result shows that most of the developing countries are suffered quite a certain passive influence, with a decrease of output, terms of trade and other economic indexes. The economy of China will suffer the most serious loss among these developing countries, with a drastic drop in the output of mineral processing and metallurgy, plastics and rubber industry, mineral extractionand, and so on. By contrast, the loss of the low-lever developing countries is not very significant. The simulation result also shows that under such scenario setting, EU will benefit much more than US, which may explain the enthusiasm of EU in carrying out the carbon tariff policy. In the negotiation of countering the carbon tariff policy of the developed countries, the high-lever and mid-level developing countries can be regarded as the appropriate partners of China for their common geopolinomic interest, while the low-lever developing countries will probably not ally with China to oppose the carbon tariff policy imposed by the developed countries. It is worth noting that US can possibly be courted by China, since US benefit little from the carbon tariff policy as a matter of fact.
